Online Slots by categories

What kind of online slot games would you enjoy playing at home or on the go? You'll want to check out our top online slot categories if you play slot machines.

What are the Top Online Slot Categories?

When searching for specific online slots, you can discover new slot categories & variations of slot games. New Slot Categories are created when original online slots are newly released. We review each category and apply our TrustRange algorithm score. As a result, we’ve created a comprehensive slot category guide to help you identify your perfect online slot game.

What Makes a Top Slot?

The minimum you can expect from modern online slots is a great design, interface, gameplay and theme. However, in our Slot Category reviews, we list several other factors that need to get examined.

High RTP 

Return To Player (RTP) is a term that defines how much a slot machine pays out to players over a significant number of spins, usually stated as a percentage. For example, a slot with a 97% return on investment (RTI) will return £97 for every £100 wagered. So, this information essentially explains how much money you can expect when playing a specific slot machine.

It’s vital to remember that this percentage is derived from millions of spins. Anything can happen in a short session of a few hundred or a few thousand spins, making slots intriguing.

Online Slot Volatility 

Volatility and variance describe the frequency of payouts, the amount paid out, and the level of risk involved in an online slot game. Simply put, volatility determines whether the slot machine you choose to play is a high, medium, or low-risk game.

Volatility (or variance) measures can help you select the ideal slots and better understand how much your risk factor while playing slots.

If you have a limited budget, you’ll want to play slots machine with lower variance, allowing you to play for more extended periods with smaller but more frequent wins. On the other hand, if you love taking chances and have a bigger budget, you should play medium to high volatility slots, delivering significant wins at a slower rate.

Which Online Slots Are The Best?

The answer to Which is the Best Online Slot is simple. It’s all down to player preference. Some players enjoy playing a variety of slots. Others stick with their favourite slot games. The Best Online slot, in our opinion, provides entertainment and good RTP.

There are many slot games over the years that have proven to be extremely popular. Two Slot games, in particular, stand out for us. They are the Immortal Romance Slot and the Thunderstruck 2 slot game. Both have great bonus rounds and features, and both are high-variance games. That means significant amounts can get claimed on them. Microgaming also creates both these slot games.

How Online Slots work?

Online Slots work in precisely the same manner that standard land-based slots work. However, these online machines' game mechanics and RTP are electronic. Both Land Based & Online Slots use a Random Number Generator formula that determines each spin's outcome. The RNG is the heartbeat of every slot game and is used to control the wins and losses of a slot game.

Which online slots have the best pay-out?

Selecting an Online Slot based on the Best Payout factor is a bit of a double-edged sword. Firstly what does Best Payout mean? Does it mean the amount you can win in a single spin or the maximum amount you can win? Or does it mean the best RTP?

We think that it is all of the above. Choosing an Online Slot that you will have fun in and be in with a chance of winning some cash is essential. Traditionally Online Slots boast bigger chances to win significant amounts per spin & for the maximum prize amount. Usually, Casinos will have an RTP page that will indicate what the Return to Play for a particular slot game was in the previous period.

RTP is a significant factor to look at when playing slots and volatility, as this will always give players an idea of what slot game to play. Best Payout Slots is challenging, but we advise you to always look at the Return to Play on Slot Machines.

How to Win on Online Slots?

There is no secret formula for winning at online slots. However, there is one factor and one alone that determines this. It’s called Luck. Online Slots at regulated casinos undergo rigorous testing before release. That means the game mechanics can not get manipulated by either the player or the casino. So winning on slots is down to a combination of factors. First, make a Deposit and select and play a game. The rest is down to the gods of fortune.

Regular Online Slot players do like to target New Online Slot releases. There have been instances where a new slot game has gotten released with a bug or two. However, it has led to some interesting situations within the online casino world.
